Application filed October 16, 1885. Serial No. 180,073. (No model.)

To all whom, it may concern.-

Be it known that I, CHARLES B. BIRD, a citizen of the United States.residing at Sioux City, in the county of Voodbury, State of Iowa, haveinvented certain new and useful Improvements in Suspender-Buckles; ahd Ihereby declare the following to be a full, clear, and exact descriptionof the same.

My invention relates to buckles for securing the end to the strap ofsuspenders, and more particularly to the class in which means areprovided whereby the reach may be separated from the strap withoutremoving the buckle from the latter; and the object of my invention isto provide a buckle of this nature simple in construction, with thesmallest possible nu m ber of parts, and in such a way that the partsmay be made readily and at a minimum cost.

To this end my invention consists in a buckle comprising a slide for thestrap and a clamp for the purpose of retaining the strap in its adjustment in the slide, which shall constitute at the same time aconnection between the buckle and the reach and a cast-off whereby thereach may be detached from the buckle.

Referring to the elevation of my device in its approved form, and Figs.2 and 3 details.

A is the slide, made ofasingle strip of metal, bent asshown. This slidehas a part cutaway, the sides being converging, as shown at t, and isfurther provided with the transverse recesses s s, forming extensions ofthe cut-away part tand leaving the shoulder r. A convenient way toconstruct the slide is to stamp the metal strip before bending, so as toleave at each end the configuration necessary to form the cut-away t,recesses s s, and shoulder when the strip is bent over to cause the endsto meet and form a slide.

B is the clamp or bearing-tongue,which constitutes at the same time aconnector and a cast-off. The clamp comprises the plate 10 and head 0,and is provided with recesses n at the junction of the extension andplate. The plate is provided with means of attaching the reach to it,which means may consist in the slots arranged in the outline of atriangle, as shown, or any other form. The head 0 is bent to project atabout a right angle from the plate, to constitute the bearing end of thedrawings, Figure 1 is an clamp, and may or may not be provided with aserrated bearing-edge. The width of the plate between the inner ends ofthe recesses n is greater than the width of the cut-away part of theslide between the shoulders r, and less than the cut-away part betweenthe inner ends of the recesses s s, the latter being less in width thanthe head 0.

As thus constructed, the operation of the device is as follows: Theplate B, having the reach attached, is inserted into the recess 8 in anoblique direction, as shown in Fig. 2, the head 0 being within theslide. The width of the plate between the recesses n being very littlegreater than the width of the cut-away between the shoulders r, theprojection of the plate into the recess 8 permits its passage betweenthe shoulders iuto the position shown in full lines in Fig. 1. By thisconstruction the clamp is capable of a movement, as on a fixed pivot, inthe recesses s s, as will readily be seen.

To remove the clamp it is necessary to lift the free end of thebearingtongue to a position substantially at a right angle with theslide, push the plate farther into one of the slots, .5- or s, and raisethe opposite end of the plateinto the oblique position shown in dottedlines in Fig. 1. The width of the head 0 being greater than the widthbetween the recesses s s, the removal of the clamp, except in the mannerdescribed, is impossible.

A device thus constructed provides all the essentials to a buckle of thecharacter named, while employing but two parts, each of which is capableof being made at a minimum cost. I do not, however, limit myself to thespecific construction shown, as various modifications may readily beconceived, the broad feature of my invention being the construction of abuckle having a clamp detachably connected therewith, therebyaccomplishing the triple purpose of a clamp, connector, and cast-ofl1\Vhat I claim as new, and desire to claim by Letters Patent, is
